Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00324 (0.00154 - 0.00681), b=3.05 (2.86 - 3.24), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.17 se; based on food items.

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100).
